Carlo Curino commented on YARN-5634:
------------------------------------
The current patch is rebased after YARN-5391 got in. I also extended the test
coverage (spotted and fixed a potential, though not likely, NPE in
FederationStateStoreFacade) and added a PriorityBroadcastPolicyManager to
experiment with simple and different router policies.

> The current set of policies require some machinery to (re)initialize based on
> changes in the SubClusterPolicyConfiguration. This JIRA tracks the effort to
> hide much of that behind a simple RouterPolicyFacade, making lifecycle and
> usage of the policies easier to consumers.
